I wasn't sure if you provided the right IP (I mean, you could have put in Monkeyboy's and I'd have accidentally banned him instead). Plus I'm not certain banning his IP would stop him from sending PMs, I'm only presuming it would as presumably there must be a way to stop him from doing it and you can't ban a person any more fully.

Although I think that since Dogz can only ansver to existing PM's, Adam could empty his PM inbox (to my understanding he could do it) and hence put an end to this menace.
